ALEXANDER BARTLETT, OF OHATHAM, ONTARIO, CANADA.

CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 245,431, dated August 9, 1881,

Application filed February 14, 1881.

To all zo/tom 'it may concern Beit known that I, ALEXANDER BARTLETT, a British subject, residing at the town ot'Ohatham, in the county of Kent, iu the Province of Ontario, Canada, have invented a new and uset'ul Improvement in Oar Ooul'iliugs, Ot' which the following is a speciticatiou.

My invention relates to that class of couplings known as self-couplers g and the ob io ject of my invention is to provide a coupling simple iu construction, and so arranged that it shall contain no springs or small parts which are liable to become deranged h v rough usage. l attain these objects in the manner illustrated in the accompanying drawings, in which- Figure l is a transverse vertical section through the center ot' a coupling` embodying my invention. Fig. 2 is an elevation ot' the same, and Fig. 3 is a plan showing` the hinged weight.

Similar letters ot' rei'ereuce indicate corresponding parts in all the iigures.

In the annexed drawings, Ais thedraw-head, the mouth ot' which is made daring, as usual, for theready insertion of the link G iu coupling.

Transversely through the upper forward part ot' the draw-head is inserted a bolt, a, which serves as a fulcruln or hinge for the bil'urcated or horseshoeshaped weight E, which rests wholly within the draw-head, as shown in Fig. 1. Upon the middle of bolt a., between the eyes e c of the bt'urcated weight E, is hinged the draw-piu D, which has a rearwardly extending arm or lever, D, extending up through the slot or opening in the root' of the drawhead, and has an eye at its outer end for the attachment of a rod or chain. The lower end of the draw-boltB impingcsuponalip orshoulder, I), in the front part of the draw-head, back ot' its tlaring mouth.

When the link O is inserted into the drawhead it pushes the draw-bolt B back, as shown in dotted lines, and lifts the rear end ot' the bit'urcated weight E, which, by resting upon or bearing against the end of the link, serves to keep this in a true horizontal position, as shown by dottod lines in Fin'. 1.

The peculiar shape of the weight, which conforms to the shape of' the inserted end ot' the link, gives ita true bearing upon the latter, so as to keep it steady, aud this shape also permits ot' the insertion and easy working ot' the draw bolt B with its arm D, which, while it has a free motion in a vertical plane, is prevented t'roin lateral play upon the bolt c by the ehves or hinges c c ot' weight F.

Having thus described inyinvention, [claim and desire to secure hy Letters Patent ot' the United States- In a carcoupling, the combination oi' the chambered draw-head A, having holt a., horseshoe shaped weight E, hinged upon boltet b v its eyes c c, and draw-holt D 13, hinged upon holt a between the arms and eyes ot' weight E, suhstantially as and for the purpose herein shown aml specified.
